[Bug 1265544] Re: 8086:0a16 [UX302LG] black screen on boot 3.12.0-7

 

Can you provide some information on the status of the patch with regards
to getting it merged upstream? Has it been sent upstream, what sort of
feedback has it received, is it getting applied to a subsystem
maintainer's tree, etc?

People affected by this bug are probably wondering why the kernel team
doesn't just apply the patch and fix it. The reason is that the kernel
team is reluctant (not opposed) to apply any patch to a stable kernel
that is not from upstream. Applying patches that don't come from
upstream add greatly to the support of the kernel as other upstream
patches may touch the same area as the non-upstream patch and may
prevent them from applying cleanly.

To submit your patch, send your patch with the detailed
description/changelog and your Signoff (ending with Signed-off-by: your
name <email>), to the emails listed from ./scripts/get_maintainer.pl
drivers/SUBSYSTEM-DETAILS (the get_maintainer.pl is from the kernel
sources). Once you have sent the patch upstream and it's accepted,
please drop a note here so that we can cherry-pick/include the patch
into Ubuntu kernel.
